How to create tiered VV with adaptive optimisation.

[taho]

Hello
I am trying to find out how to implement the subject.
Our company has 3par InServ F400 with dynamic and adaptive optimisation licenses (w/o thinly provisioning stuff). So after reading manuals and browsing web i can't understand some points ... may be more
My questions relies on below statements:
1) My aim is to create a virtual volume consisting different chunklets from SSD,FC and NL disks
2) Having license to adaptive optimisation i hope it will work automatically for newly created disks
3) I can create a virtual volume only by createvv command.
4) And this implies to select only one CPG from which the user space will be allocated.
5) in help manual "help createcpg" i have found that
The -devtype pattern cannot be used to mix Nearline (NL), FC, and Solid State Drive (SSD) drives.
Therefore I can create CPG only with one type of drives. (Am i right here ???)
6) Finally every virtual volume that i have created has only one type of drives.
Please help me understand what i am missing to use adaptive optimisation that require tiering.

Sorry for my English.

First you set up three CPGs, one for each type of disk. Then you configure AO with these CPGs as your three tiers. AO will then monitor the data within these CPGs and move blocks between them. So data that is accesses frequently will be moved to the CPG on SSD while stale data will move to the NL-CPG.

Volumes don't really know anything about Adaptive Optimization (AO). So you create your volumes on one of the three CPGs that will then act as the default destination for new data. The same goes for the snapshot-CPG that you can also set when creating the volume.
Volume-data that appears in the default CPG is then getting the AO-treatment as described above. And don't worry, the volume will be able to find its own data even if AO has moved it from the default to one of the other CPGs.

Thank you very much for explanation of AO! A new question is how to configure AO from cli. Do you know command name to perform above? Seems I missed something in help guide of 'InServ Cli'.

AO is configured from the System Reporter page.
Go to Policy Settings -> Adaptive Optimization Configuration

Another thing about AO is that it has nothing to do with InServ or the 3PAR itself. AO is part of the System Reporter (SR) and is therefore also configured via SR's webinterface (see "Policy Settings"). SR regularly asks the 3PAR for all kinds of statistics, including the stuff needed to do storage tiering. Within the database of these stats AO then looks for data that should be moved to other tiers and sends corresponding move-commands to the 3PAR. In the InServ-CLI you can see these moves as "move_regions" tasks via showtask.
